Abstract

Zinc Sulphide is one of most studied semiconductor with wide band gap (3.5–3.9 eV) versatile material due to its physical and chemical properties. ZnS is a non-toxic material and a suitable candidate to be a buffer layer for heterojunction solar cells. In this study, Zinc Sulphide (ZnS) thin films were deposited by chemical bath deposition technique using Zinc Acetate Dihydrate [Zn (CH3COO)2. 2H2O] and Thiourea [CH4N2S]. The ZnS thin films samples were characterized by UV-Vis NIR Spectroscopy, X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDX), Fourier-Transform Infrared Spectroscopy (FTIR) and Thin-Film Measurement Instrument. FTIR spectra confirmed the presence of ZnS bond in the crystalline thin film. XRD data confirmed the cubic structure of the deposited thin film only when the amount of Thiourea was increased and the complexing agent Hydrazine Hydrate was replaced with Tri-Sodium Citrate. Crystallite size and strain were estimated using Debye-Scherrer model and Williamson-Hall model and lattice constant was estimated using Nelson-Riley plot. Otherwise, XRD showed the amorphous phase. UV-Vis data confirmed ZnS thin films as enough transmittive and it showed higher bandgap. Thin-Film Measurement Instrument was used to measure the thickness of the ZnS thin films. Synthesized ZnS thin films exhibited promising characteristics for using as the buffer layer of the heterojunction solar cells. Highlights • ZnS thin films were prepared successfully by simple, low cost and environment friendly chemical bath deposition method. • XRD measurement confirmed both Amorphous and Crystalline phase of ZnS thin films. • By changing the precursor only can be achieved crystalline phase from amorphous phase of ZnS thin film. • The amount of precursor and deposition conditions can be optimized to produce crystalline ZnS thin film.

化学浴沉积法合成太阳能电池缓冲层用ZnS薄膜性能的表征与优化
硫化锌由于其独特的物理化学性质,是目前研究最多的宽禁带半导体(3.5 ~ 3.9 eV)通用材料之一。ZnS是一种无毒材料,是异质结太阳能电池缓冲层的理想材料。本研究以二水合乙酸锌[Zn (CH3COO)2]为原料,采用化学浴沉积技术制备了硫化锌(ZnS)薄膜。和硫脲[CH4N2S]。采用紫外-可见近红外光谱(UV-Vis NIR)、x射线衍射(XRD)、扫描电镜(SEM)、能量色散光谱(EDX)、傅里叶变换红外光谱(FTIR)和薄膜测量仪对样品进行了表征。FTIR光谱证实了晶体薄膜中存在ZnS键。XRD数据证实,只有增加硫脲的用量,并用柠檬酸三钠代替水合肼络合剂时,沉积的薄膜才具有立方结构。采用Debye-Scherrer模型和Williamson-Hall模型估计晶体尺寸和应变,采用Nelson-Riley图估计晶格常数。另外,XRD显示为非晶相。UV-Vis数据证实了ZnS薄膜具有足够的透光性和较高的带隙。采用薄膜测量仪测量了ZnS薄膜的厚度。合成的ZnS薄膜具有作为异质结太阳能电池缓冲层的良好性能。•采用简单、低成本、环保的化学浴沉积方法成功制备了ZnS薄膜。•XRD测量证实了ZnS薄膜的非晶相和晶相。•仅通过改变前驱体就可以使ZnS薄膜由非晶相转变为晶相。•可以优化前驱体的用量和沉积条件来制备结晶ZnS薄膜。

期刊介绍: Main Group Chemistry is intended to be a primary resource for all chemistry, engineering, biological, and materials researchers in both academia and in industry with an interest in the elements from the groups 1, 2, 12–18, lanthanides and actinides. The journal is committed to maintaining a high standard for its publications. This will be ensured by a rigorous peer-review process with most articles being reviewed by at least one editorial board member. Additionally, all manuscripts will be proofread and corrected by a dedicated copy editor located at the University of Kentucky.
